[0036] like Figure 1-Figure 2 As shown, one embodiment of the present invention is:

[0037] The novel test probe automatic assembly device comprises a core feeding mechanism 2, a stabilizing mechanism 3, a cutting mechanism 4 and a needle tube feeding mechanism 5 which are sequentially arranged on a workbench from left to right and respectively connected to a driving mechanism 1. The driving mechanism 1 is used to simultaneously drive the core feeding mechanism 2, the stabilizing mechanism 3, the cutting mechanism 4 and the needle tube feeding mechanism 5 to work at a predetermined beat. The core feeding mechanism 2 is used to feed the needle core into the cutting mechanism 4, which is cut into probes of equal length by the cutting mechanism 4. The stabilizing mechanism 3 is used to fix the needle core when the cutting mechanism 4 is cutting, so that the needle core remains stable. The needle tube feeding mechanism 5 is used to feed the needle tube and cooperate with the core feeding mechanism 2 to insert the needle core into the needle tube. The core feeding mechanism 2 comprises:

[0038] The guide rail 21 is horizontally arranged on the workbench in the left-right direction;

[0039] A slider 22 is slidably disposed on the guide rail 21;

[0040] The fixing seat 23 is arranged on the slider 22, and a needle core channel is opened in the middle thereof;

[0041] The clamping seat 24 is floatingly arranged at the rear side of the slider 22 and is slidably connected with the fixing seat 23, and is used to cooperate with the fixing seat 23 to clamp the needle core;

[0042] The pushing device 25 is arranged at the left end of the guide rail 21 and is connected to the driving mechanism 1 and the fixing seat 23 respectively, and is used to drive the slider 22 to move back and forth along the guide rail 21;

[0043] The holding seat 26 is slidably arranged on the workbench at the rear side of the guide rail 21 along the front-rear direction. The rear side of the clamping seat 24 is rotatably provided with a roller 28, and the roller 28 is in rolling connection with the clamping seat 24. When the fixed seat 23 and the clamping seat 24 move along the guide rail 21 toward the cutting mechanism 4, the holding seat 26 moves forward to keep the clamping seat 24 moving toward the side of the fixed seat 23, thereby clamping the needle core in the needle core channel.

[0044] The first transmission device 27 is connected to the driving mechanism 1 and the holding seat 26 respectively, and is used to drive the holding seat 26 to approach or move away from the roller 28.

[0045] During operation, the external core feeding device passes the needle core through the needle core channel between the clamping seat 24 and the fixed seat 23, passes through the stabilizing mechanism 3 and enters the cutting mechanism 4. The first transmission device 27 controls the holding seat 26 to move forward, pushing the clamping seat 24 to the side of the fixed seat 23. The driving mechanism 1 drives the pushing device 25 to work, and the pushing device 25 pushes the slider 22 to move along the left end to the right end of the guide rail 21. At the same time, the roller 28 rolls along the front end of the clamping seat 24 to keep the clamping seat 24 and the fixed seat 23 clamped. At this time, the needle tube feeding mechanism 5 feeds the needle tube to the position corresponding to the right end of the cutting mechanism 4. After the needle core passes through the cutting mechanism 4 and is inserted into the needle tube in the needle tube feeding mechanism 5, the stabilizing mechanism 3 fixes the needle core, and the cutting mechanism 4 cuts off the needle core. The probe assembly is completed, the needle tube feeding mechanism 5 releases the needle tube, and the probe falls into the unloading station.

[0046] The present application drives the core feeding mechanism 2, the stabilizing mechanism 3, the cutting mechanism 4 and the needle tube feeding mechanism 5 to work simultaneously through the driving mechanism 1, pushes the retaining seat 26 and the clamping seat 24 to work through the first transmission device 27, and cooperates with the fixing seat 23 controlled by the pushing device 25 to cooperate with the needle tube feeding mechanism 5 to insert the needle core into the needle tube, and cuts the needle core into a fixed length through the stabilizing mechanism 3 and the cutting mechanism 4, thereby realizing the automatic assembly of the probe, solving the problem of complicated cutting, arrangement and transportation of the original probe, and improving the production efficiency and yield rate.

[0048] When working, the driving motor 10 rotates and drives the first sprocket 15 and the first bevel gear 13 to rotate at the same time, and the first bevel gear 13 drives the second bevel gear 14 to rotate, thereby driving the first driving shaft 11 to rotate, and then drives the first cylindrical bevel gear 16 to rotate, and then drives the second driving shaft 12 to rotate through the second cylindrical bevel gear 17;

[0049] In one embodiment, Figure 2 As shown, the pushing device 25 includes a rotating shaft 251, a rotating wheel 252 and a first connecting rod 253.

The second transmission device 34 is respectively connected to the driving mechanism 1 and the slide 33, and is used to drive the slide 33 to reciprocate, thereby driving the top end of the abutting seat 32 to approach or move away from the stabilizing seat 31.

[0052] During operation, the driving mechanism 1 drives the slide 33 to move forward through the second transmission device 34, and the slide 33 drives the top of the abutment seat 32 to move forward, thereby cooperating with the stabilizing seat 31 to clamp the needle core. After the cutting mechanism 4 completes cutting, the second transmission device 34 drives the slide 33 to move backward to facilitate the operation of the core feeding mechanism 2. The elastic connection between the abutment seat 32 and the slide 33 can avoid deformation of the needle core caused by excessive clamping force, and can adapt to needle cores of different thicknesses.

[0054] During operation, the needle core passes through the through hole 421 and the cutting channel 441 in sequence, and the driving mechanism 1 drives the knife plate 44 to slide in the knife seat 43 through the third transmission device 45.

[0062] During operation, the driving mechanism 1 drives the third driving shaft 57 to rotate, thereby driving the second end of the swing arm 58 to make a circular motion. The swing arm 58 drives the first slide 52 to move forward and backward in the first bracket 51 through the second connecting rod 59, and then drives the second bracket 54 to move forward and backward. When the second bracket 54 moves forward and backward, the guide wheel 56 rolls along the different undulating trajectory segments on the top surface of the track 55, so that the second slide 53 slides vertically in the second bracket 54, and drives the material picking seat 61 to realize the movement in the front, back, up and down directions through the cantilever 60.
